Prevalence of Echocardiography Use in Patients Hospitalized with Confirmed Acute Pulmonary Embolism: A Real-World Observational Multicenter Study

Acute pulmonary embolism (PE) carries an increased risk of death. Using transthoracic echocardiography (TTE) to assist diagnosis and risk stratification is recommended in current guidelines. However, its utilization in real-world clinical practice is unknown. We conducted a retrospective observational study to delineate the prevalence of inpatient TTE use following confirmed acute PE, identify predictors for its use and its impact on patient's outcome. Clinical details of consecutive patients (2000 to 2012) from two tertiary-referral hospitals were retrieved from dedicated PE databases. All-cause and cause-specific mortality was tracked from a state-wide death registry. In total, 2306 patients were admitted with confirmed PE, of whom 687 (29.8%) had inpatient TTE (39.3% vs 14.4% between sites, P
